Does anyone do this, and if so how? I have tried sudo apt-get update, then sudo apt-get upgrade firefox but that starts the whole Upgrade process.

Do I have to do a full Install of Firefox to get the newest version?

I'm curious about this from a security standpoint, and am not sure why it is not suggested by all these sites that say to use LiveDVD's for Bank Transactions? Goes against everything I have read about Browser Security.

This will update your package lists so you can get the most recent version of Mozilla Firefox available in the repos.
2. In your terminal type:

sudo apt-get install firefox

This will download and install the most recent version of Mozilla Firefox listed in your package list, unless it is already installed.
3. (Optional) In your terminal type:

sudo apt-get clean

This will clean APT's cache. When you run a command like "sudo apt-get install firefox" firefox and any dependencies that need to be
downloaded get saved to APT's cache folder, but the system doesn't automatically delete them. Since you're running a liveUSB presumably
with persistence you probably don't want to keep those cached files, because it's more data being saved to the persistence file/partition.

Running from a frugal environment (eg: a live-DVD) is often recommended by people because it helps ensure you are using an uncompromised (eg: not infected with malware, or hacked) OS, and because data from the session is only written to memory, it is physically erased when you reboot, so there are no traces of your activity for someone examining your computer to find. Please note, that by using a persistence file/partition, or by having an in-use swap partition, you potentially lose these advantages. Most people just use their regular OS, delete their browser cookies, clear their passwords, and clear their history, but if you're looking to up your level of security, using a frugal environment (eg: a live-DVD) is a popular next step.

That's perfect hollowface, thank you very much and have a happy Gobble Gobble Day!

EDIT: I will be using this for the LiveUSB, and with your instructions also with the Persistence Mode. Still working out the Persistence Install. The one I made worked perfectly but was way to slow. Wiz has turned me on to some (new to me) Instructions that might help, along with using the (new to me) Unetbootin that is much faster than the other installers I've tried.

Still looking into all this Adobe Flash Player, and Firefox stuff via LiveLinuxUSB. Sorry I'm a little slow to grasp it all, so posting some links to review later and get input.

It's not critical but trying to understand why Linux Mint has issues with Flash Player and Ubuntu don't, something to do with Licensing I guess. I use Chomium in Mint to avoid this, and install pepperflashplugin-nonfree. Also tried the instructions from hollowface but did not work for me, will have to revisit and try again.

Having trouble focusing right now Nick and this subject was secondary at the moment. I posted that as I stated, but also because I was stuck without a way to save that site and that screenshot because did not have a spare usb drive to save that stuff over to.

This is my main objective though: Just to be able to use Firefox (or whatever is fastest in LiveUSB) so that I can use the Live Environment efficiently. Installing Chromium works well but it is a few extra steps. If could just use firefox would be better. Luckily Firefox works well in Ubuntu! but not in Mint. So to test things out in Mint (Poor mans Virtual Machine) just want a simple way to do so. If I remember correctly - the flash player is installed by default in Mint??? So why don't FF work then LOL.

Not real important guys so don't waste time if you don't have it, I will figure it out eventually. I will try Ubuntu Restricted Extras Nick - but surely looking for a quick fix considering installing in the Live medium is lost, Persistence is WAY TO SLOW, done with all that.

Note there was a spelling mistake in that command which I've now corrected.

I'm on Kubuntu at the moment and it doesn't have ubuntu-restricted-extras installed, but I checked and it's in the repositories. (I'm not sure why it's not installed, but Kubuntu doesn't seem to need it as it plays everything I throw at it).

One of the "20 things to do after installing Mint" on BinaryTides is to install ubuntu-restricted-extras.

Thanks for the link!!! Yes, I expect that Kubuntu, Ubuntu based - would not need this as it only seems to be an issue with Mint in Live environment, if Chrome is installed it is fixed with the included plugin - at least with full install as you know.

Was not succesful Updating Firefox but did get the flashplayer plugin installed but it's probably not worth it, just install chromium and pepperflash. I guess if you have the file on a usb you can quickly drop it into /usr/lib/mozilla/plugins/ and use firefox on youtube. Isn't there an easy way to do this in a Live Enviroment?

I'm guessing one would have to remove Firefox before installing the newer one, will revisit that later with hollowfaces instructions again.
